Oregon Tax Structure

Corporate income tax single sales factor

The tax rate on corporate income of firms doing business in the state is the greater of a minimum tax based on relative sales ($150-$100,000 - approximately 0.1%) or an income-based levy of 6.6% up to $250,000 and 7.9% above that. (This second tier switched to $10 million in 2013).

Oregon businesses are taxed on a portion of their total income derived from sales within the state.

This corporate income tax is considered single sales factor tax; it only considers Oregon sales in determining corporate income taxes owed to the state.

Other states often include additional assets and payroll, making them "multi-factor" taxes.

Tremendous impact for Oregon multi-state companies

If a company is headquartered in Oregon but sells products throughout the country, or world, it only pays Oregon corporate income tax based on the amount of income coming from sales within state lines.

How the tax works

First the state looks at the company's entire federal taxable income, total sales and portion of sales derived in Oregon.

Second, the state takes the ratio of Oregon sales to total sales and applies that same ratio to the company's total federal income.
